Hello.
Here's some background:
1. What kind of vehicle you have
Chevrolet Corvette 1986 L98 ie. 350 TPI, 65 tml
2. What your owner's manual says
Sorry, no manual, just 5W-30 info on oil cap
3. Where you live
Northern Europe, will run it only in the summer in temp range of 40...90F
4. How you drive (easy? hard? fast? slow?)
Easy driving around town and highway, some blasts trough the twisties and a relative easy track day or two in the season.
5. What your daily drive is like (short trips? long trips? city? highway?)
Mostly short trips in the city/highway. Also longer highway trips on vacation when touring.
6. Whether your car has any known problems
No engine problems. Previous owner has used Kendall GT1 5W-30.
--------------------------------------------------------------
Right. I could use some advise on what oil to use. I'm switching away from previous owner's Kendall because it is not available easy and it costs more than Mobil 1 0W-40.
Over here there are couple of 5W-30 oils available on the shelf but they tend to be Long life types. These are such as Mobil ESP, Castrol Edge, Valvoline Synpower, Shell Helix and some local brands such as Teboil Diamond and Neste. Also GM 5W-30 Longlife is available easily.
If you recommend me to stay with 5W-30 is there a brand you would recommend for me? 5W-30 oils such as Redline and Royal Purple are not available here.
It seems that the most common weight over here nowadays is 5W-40 and just about any of the bigger names have their products available in this weight such as Shell Helix in several types, Mobil Super 3000, Castrol Magnatec etc. Also some brands in 0W-40 weight, too.
Given the background above and info on what is available (just few listed) I'd like to ask whether:
- I should stick with the 5W-30 -> which one?
- switch to 5W-40 -> which one?
- what about 10W-40? Redline and Brad Penn available
I fear I'm overthinking this matter ie. does the brand/type/weight matter at all for this old engine?
Thank you for your patience.
